USC’s passing attack is looking better behind the leadership of redshirt sophomore quarterabacks Cody Kessler and Max Wittek and that means at least one thing: the secondary is struggling.

Trojans coach Lane Kiffin expressed his concern after Saturday’s 52-play scrimmage, according to the Los Angeles Times. Torin Harris, Anthony Brown and freshman Chris Hawkins had a difficult time Saturday containing a USC receiving corps that was without its biggest playmaker, Marqise Lee, who is sidelined with a knee injury.

Kessler hit Nelson Agholor for a 58-yard scoring strike and added a TD pass to Victor Blackwell, while Wittek completed three passes for 84 yards.

“We’ve got the big men up front giving it all they got and then on the back end we gave up a few big plays, which can’t happen,” safety Josh Shaw told the Times. “You’ll lose a ballgame like that.”

USC is playing with two early enrollee freshmen in the secondary at safety in Hawkins and safety Su’a Cravens. Also, sophomore cornerback Kevon Seymour is out with an ankle injury.

Kiffin said the final two weeks of spring practice and fall camp will be pivotal for the Trojans secondary.

“They’re not going to come out of somewhere,” Kiffin told the Times. “So we’ve just got to play better with the guys we have, get them better and coach better.”
